To all whom it may concern: 'Be it known that I, JOSEPH P. CLEAL, a

citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Vibratory Chucks, of which I declare the following to bea full, clear, and exact description.

A This invention relates to vibratory chucks or tool-holders it beingamong the objects of this invention to impart to such chucks a vibratoryor shaking movement simultaneously with theordinary revoluble movementof the same about its normal axis of rotation whereby to prevent thecontinued maintenance of a fixed axis of rotation, Such an Improved formof chuck having this particular movement may be available forandespecially adapted to various sorts of work but in the presentinstance the particular use which is made of such a chuck is inconnection with a so-called tablet-indicator shaking machine by means ofwhich machine the tablet-indicators in common use in cash registers are,after having first i been dipped in a bath of paint or ink, then shakenin this peculiar manner by this ma- ,chine so that all surplus ink isthrown off from the indicator and the ink remaining on the surface oftheindicator is spread out into a perfectly smooth and evenly distributedsurface or layer of ink, and

these indicators when thus covered with 3 a film ofink may after dryingbe printed upon with a', different colored ink to show 1 the ordinaryfigures customary on these tab let-indicators, and by this process theold "method of pasting paper figures on such indicators isentirelydispensed with. The

peculiar advantage of this vibratory chuck in this. particularconnection is as follows: If the tablet-indicators were revolved aboutan axis which extended through somev portion of the indicator thisaxis'of rotation becomes a dead-line or a line .of'nonmovement and givesuse to a rldge of 1nk settling thereon, which of course, destroys theevenness of the ordinarily flat surface of the indicator, whereas ifconcomitantly with the rotary movement ofthe chuck which holds' theindicator a vibratory movement ,is also imparted thereto, this willprevent the establishment of a fixed axis of rotation and willpreventthe formation of any such ridge and will permit the ink to beevenly distributed over the surface of the indicator.

With the above enumerated objects in view, and with other objectsincidental thereto, this invention comprises certain novelconstructions, and combinations of parts, the essential elements ofwhich will be recited in the appended claims, and a preferred form ofembodiment of which will now be described in the following specifieation and set forth in the accompanying A drawings.

Of said drawings: Figure 1 represents a front elevation of the duplexindicator shaking machine to which these improvements are applied. Fig.2 represents a side elevation of the same. Fig. 3 represents a detailtopplan of that portion of the. machine comprising the main driving shaft.

Figs. 4 and 5 represent detail views of the clutch mechanism used inconnection with the main driving shaft, and Fig. 6 shows a detailsectionalized View of the vibrator chuck mechanism.

As above stated this improvement may be applied on any of the variousforms of machines in which a tool or work holding chuck is given arevoluble movement, and

only so much of the general construction of the present machine as showsthe nature of this particular invention need be described in detail. 7

As shown in Fig. 1 the machine is constructed in duplex form, and sincethese two parts are the same, only one part will be" described'indetail. A driving motor 10 imparts a rotary movement to the shaft 11,

which through suitable. worm gearing gives a continuous revolublemovement tothe mainydriving shaft 12.. Runninguponone end of this shaft12 is a belt 13 which drives an auxiliary shaft 14 carrying cams 15 and16. for the purpose which will later be described.

As shown in Figs. 3, 4 and 5 the driving that the proper movement ofeither lever 23 will carry its respective beveled collar outward so asto cause the clutch jaws to engage the sleeves 23 loosely mounted on theshaft 12 so as in effect to couple the revoluble shaft 12 to the sleeve23 and impart a continuous revolution thereto, and this sleeve 23carries a worm gear 24 which meshes with a horizontal gear 25 which isfast to and carries with it an upright collar 30 (see Figs. 1 and 6)which collar 30 is formed at its lower end to hold a vibratory chuck 31.An apron 32 extends downwardly from the under side of the collar 30 andcarries a screw 33 which projects into and forms a pivot for a chuck 31,and the reduced upper end of the chuck extends up into the collar 30 andcarries two pins 34 between which extends the reduced and inclined end35 of a vertical shaft 36. shown) fast on the inside of the collar 30projects into a groove 37 formed in the shaft 36 so that the shaft 36will revolve with the collar 30, and of course also with the chuck 31which is also carried around with the collar 30 in its revolvingmovement. The shaft 36 is given a reciprocating movement vertically, bymeans of the aforesaid cam 15 carried by the shaft 14 (see Fig. 1) andthe shaft 36 is normally held in upper posit-ion by a spring 37 suitablycoiled between the upper collar 38 fast to the shaft and a lower collar39 fast to a nut carried on the upper end of the aforesaid revolublecollar 30. The chuck 31 is formed with a slot 40 or other suitablerecess into which is inserted a holder 41 which is suitably clamped orheld within the chuck 30 and within which holder may be secured theparticular tablet-indicators 42 which are to be shaken in the manneroutlined above, these indicators comprising a lower flag portion and astem 43 which is led up into the holder 41 and then clamped therein bymeans of a screw 44 so as to be held firmly in the holder during thevarious movements of the chuck 31. Pails 45 are provided to surround theindicators 42 for the purpose of catching the surplus ink which isthrown off therefrom by the centrifugal force of rotation. It will beseen that this inclined portion 35 will enable a complex motion to begiven to the chuck 31, which will be rotated about a vertical axis, andalso will be rapidly oscillated about a horizontal axis. Thisoscillation is evidently caused by the inclined portion 35 by itsvertical reciprocation, since the pins 34 closely abut the portion 35 onboth sides and will be moved a distance corresponding to the divergenceof the sides of the portion 35 from a vertical line.

The operation of these parts is as follows: Assumingthat the motor shaft11 is being continuously driven and that the right hand lever 23 hasbeen thrown to the right so as to establish the clutch connection withthe A suitable pin (not.

driving shaft 12 and thereby continuously drive the collar 30, thiscontinuous revoluble movement of the collar 30 will of course carry withthe collar the chuck 31 so as to impart a continuous revolution to theholder 41 and the indicator 42, which as suggested above has alreadybeen dipped in a bath of ink and is now to be shaken to remove thesurplus ink therefrom and distribute the remaining ink over the surfaceof the flag of the indicator. 'This same revoluble movement of the shaft12 which revolves the indicators 42, also serves through the belt 13 andshaft 14 to revolve the cam 15 so as to reciprocate the shaft 36 andthis reciprocation of the shaft 36 causes its lower inclined end 35 toride up and down bet-ween the pins 34 and thereby rock the chuck 31about its pivotal screw 33 so that this rocking effect takes placesimultaneously with the revoluble movement of the chuck. It will thus beseen that the effect of this compound movement is to impart a vibratoryor wabbling movement to the'chuck and indicator, and thereby prevent themaintenance of any fixed axis of rotation extending through the flag ofthe indicator, and by this means the surplus ink will be shaken from theindicator by the centrifugal force of rotation and this wabbling effectproduces the desired even distribution of the ink over the surface ofthe indicator. Of course the operation of the other parts of the duplexmachine is precisely the same, the cams 15 and 16 being oppositelysituated on their shaft so as to produce a more even movement of theentire machine.

While the forms of mechanism here shown and described are admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat I do not care to confine myself to any one form of embodiment ofthe invention here disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.

Having thus described my invention what I claim is as follows:
